These natural deduction systems present the logic by describing introduction and elimination rules for the connectives. These rules tell one how to draw In natural deduction, the left and right sides of the sequent behave very differently : there can be many assumptions, but only one con- sequence, and while rules Let S be some natural-deduction system of propositional logic, with mech- tive or derived rule (hence having Conditional Proof as a primitive or derived rule).

For example, a0: x > 10 ∧ x < 20. It follows that the theorem q → ( q ∧ q) is not provable without ( ∧ -intro), as then so would be π ( q → ( q ∧ q)) = q → ⊥, which is not valid. Hence Natural Deduction without ( ∧ -intro) is incomplete. A similar argument can be found for the omission of other rules.
